[Bug 1060184] Re: puppet client init script pid file error

[Matthew Malkin]

After a clean install i type 
#apt-get install puppet
following which i change the line in /etc/default/puppet from START=no to START=yes

then i join the puppet client to my puppet server using 
#puppetd --server servername --waitforcert 60 --test
on the client side and 
#puppetca --sign servername
on the server side

then the following session can occur:

Description: Centralized configuration management - agent startup and compatibility scripts
 This package contains the startup script and compatbility scripts for the
 puppet agent, which is the process responsible for configuring the local node.
 .
 Puppet lets you centrally manage every important aspect of your system
 using a cross-platform specification language that manages all the
 separate elements normally aggregated in different files, like users,
 cron jobs, and hosts, along with obviously discrete elements like
 packages, services, and files.
 .
 Puppet's simple declarative specification language provides powerful
 classing abilities for drawing out the similarities between hosts while
 allowing them to be as specific as necessary, and it handles dependency
 and prerequisite relationships between objects clearly and explicitly.

as you can see, the /etc/init.d/puppet stop appears to have no effect - puppet processes remain running after it is called.

the reason appears to be because the /etc/init.d/puppet file contains the line:
PIDFILE="/var/run/puppet/${NAME}.pid"
I assume in this case ${NAME} resolves to "puppet"

therefore when it is attempting to stop puppet it searches for
/var/run/puppet/puppet.pid but the agent creates
/var/run/puppet/agent.pid

Simply changing the line in the /etc/init.d/puppet file from "${NAME}"
to "agent" should (and does) solve the problem
